Answer:
If I remember correctly, right angles are 90 degree angles. So the answers would be A. B. and C.
Step-by-step explanation:
If you see the little box on the angle, that means it's a 90 degree (right) angle.
The formula to use is A=(b1+b2)h if one base is 24 and the other one is 16 which equals to 40 when you add then you still have H which is 12 so you could either divide 12 by two to get half or multiply by 12 and then divide it
40•12=480
480 divided by 2= 240
Your final answer should be 240ft
Answer: Option B
B. 
Step-by-step explanation:
We have the following equations:
(1)
(2)
Let us call "a" the coefficient of the variable x in the first equation and call "b" the coefficient of the variable x in the second equation.
Then we must multiply the number "a" by a value z such that when adding 
the result is zero.
So
We solve the equation for z
The first equation must be multiplied by a value of
